Used in sanitary process piping for automated flow control, this Glacier Tanks 2 inch SS304 pneumatic butterfly valve features a single-acting pneumatic actuator with spring return. The valve body and actuator assembly carry part number 21CW318220 with a Rev A designation, manufactured in China for Glacier Tanks and marked SS304. Connection type is 2 inch tri clamp with a 64 mm OD ferrule, compatible with standard sanitary tri clamp fittings. The actuator is rated for an air supply pressure of 5 to 7 bar for connection and a maximum operating pressure of 9 bar (approximately 130 PSI), with a maximum output torque of 20 NM and a shut-off time of 1.5 seconds. The body is constructed from 304 stainless steel, making it suitable for food, beverage, brewing, pharmaceutical, and sanitary industrial process applications. A visual position indicator is visible on the actuator body. The 13MHP-G200 high pressure bolted tri clamp is stamped on the valve body, referencing the two-bolt clamp connection hardware used on this assembly. Single-acting actuation provides automatic spring return to the closed position upon loss of air supply, which is a standard fail-safe configuration for on-off sanitary service applications.
